How To Get There - Maps

The Middle Ages did not have maps the way we think of them. Or rather they had maps, but not for the purpose we would think of them. There were some general purpose maps that tried to show the world, or the country; maybe even a town. But a map you could use to travel from place to place easily?

Travel from village to village would be simply. You'd ask for directions from someone who'd been there. The lack of Welcome signs at the border of towns meant you should simply as the people you run into if you have reached the intended town. There might not even be a road or path; the directions might be "over the hill" or "follow the river downstream."

To get from one place to another, often the directions were simply an itinerary, a list of the towns and landmarks along the way. Some of these exist, such as the manuscript of Archbishop Sigeric of Canterbury, who visited Rome in 990; his list of churches and the route he followed is in the British Library. Many of these itineraries would probably be used once and tossed away.

Also in the British Library is the manuscript illustrated here. It is by Matthew Paris, and shows how to get from London to Rome with sketches of the places along the way!

Some trips were made solely to visit holy shrines, such as the famous shrine of St. James in Santiago de Compostela in Galicia. These places were visited by so many people that you could more easily find directions as well as traveling companions.

I want to take a closer look at Sigeric next.

How To Get There - Roads

I never gave roads much thought before. References to "The Silk Road" did not refer to a "road"; instead, it was a series of routes (and alternate routes) from one city/town to another, linking the West and the East.  I always just assumed that these were well-traveled paths. There are, however, routes that need infrastructure because the way is not easy.

One example is in areas where it is necessary to travel over wetland, for instance the Sweet Track (named for the discoverer in 1970, Joe Sweet). It allowed travelers to go from one small island at Westhay (four miles northwest of Glastonbury) over marshland to a high ridge at Shapwick to the west. Wooden posts were driven into the wet ground, and then oak planks were laid end-to-end. It allowed travelers to cover the 1.2 miles distance and stay dry. By examining the rings in the wood and comparing them to known patterns of tree rings (a technique called dendrochronology), it can be determined that the causeway was built in 3808-07 BCE. As it turns out, the Sweet Track was preceded by an even earlier system called the Post Track, which was built in 3838 BCE, which used ash planks over lime and hazel posts. This suggests a community effort to maintain the causeway over at least a couple generations. Changing climate and the drying up of some areas would have eliminated the need for some of these causeways.

The Romans were amazing road builders, and examples of their stonework can still be found throughout Europe and Great Britain. (The illustration shows a section of the Appian Way, an important Roman road in Italy.) Trade and military personnel needed to move swiftly, and the Roman Empire made sure they could. At the height of the Empire, 29 great highways led to/from the capital, helping to support the saying "All roads lead to Rome." It is estimated that 250,000 miles of roads were made and maintained, 50,000 of which were stone. Great Britain has at least 2500 miles of Roman roads. During there Roman occupation of Britain, many known pathways were paved in the Roman style. This helped passage in all weathers, since many well-worn walking routes could become muddy trails at certain times of the year.

Roman roads and timber trackways have left evidence throughout Europe. Getting from place to place over longer distances, however, required more than a smooth surface to tread. Westhay to Shapwick was easy and obvious. The Appian Way led from Rome to Brindisi in southeast Italy. What if I needed to get from Westhay to Brindisi, however? Did the Middle Ages have AAA that could create a personalized map? Let's find out tomorrow.

The Map You Walk On

Madaba, a town east of the Dead Sea, suffered from a devastating earthquake in 746 and was left to become wilderness. Centuries later, Madaba began slowly to be restored as a habitable city. In 1884, while the ancient ruins of a church were being cleared to make way for a new Greek Orthodox church, workers discovered a mosaic on the floor.

The Madaba Mosaic Map is considered a reliable source of data on Byzantine-era Jerusalem because of the detail with which it is constructed. Known old structures such as the Damascus Gate, the Tower of David, the Church of the Holy Sepulchre and others are depicted with enough detail to distinguish them from simple symbolic images. The detail even allows scholars to date the map: Jerusalem shows the Nea Church, which was built and in use by 542, but does not show any changes or structures built after 570. In fact, the Nea Church was only able to be discovered by archaeologists when they used the Madaba Mosaic as their cue for where to dig! Furthermore, the exact location of the ancient Jewish city of Askalon/Ashkelon was uncertain until the Madaba Mosaic showed where it was on the coast.

The floor mosaic faced east, toward the altar. Therefore, when one was facing the altar, one was facing in the proper direction to orient the map with the real world. All the inscriptions are in Greek. The map extends from Lebanon in the north to the Nile Delta, and the Mediterranean to the Eastern Desert. The original dimensions were 21 meters by 7 meters and would have required over 2,000,000 individual tiles, but damage over the years has reduced it by about a third, to 16x5 meters. We do know that some of it was damaged deliberately in the 8th century when Muslim rulers had depictions of people removed. Now carefully preserved, it can be seen in the Greek Orthodox Church of St George.

Finding Paradise

Higden's map,
with Eden (and East) at the top
Medieval mapmakers, if they wanted to be thorough, of course had to account for the Garden of Eden. Surely it existed somewhere in the world, but where?

It certainly wasn't in Europe, which was fairly well traveled, and so the medieval mind had to look beyond the lands they knew. The 13th century Hereford map (a mappa mundi of the T-O pattern; see the link above) places Eden on an island near India, surrounded by not only water but also a massive wall. Ralph Higden places it not only in the less-understood-to-Europeans Asia, but makes clear it is an inaccessible part of Asia (you have to explain why no one has stumbled upon it and returned with the news).

Hrabanus Maurus was a little more cautious:
Many folk want to make out that the site of Paradise is in the east of the earth, though cut off by the longest intervening space of ocean or earth from all regions which man now inhabits. Consequently, the waters of the Deluge, which covered the highest points of the surface of our orb, were unable to reach it. However, whether it be there, or whether it be anywhere else, God knows; but that there was such a spot once, and that it was on earth, that is certain. [De universo (Concerning the world)]
A German priest of the 15th century, Meffreth, seems to be the only person who thinks himself qualified to actually answer the question "Wouldn't Eden have been washed away in Noah's Flood?" He has left us a sermon in which he claims that Eden exists on an extremely tall mountain in Eastern Asia—so tall, that the waters that covered Mt. Ararat merely lapped at the base of Eden on this mountain. He further explains that four rivers pour from Eden at such a height that the roar they make when descending to the lake at the foot of the mountain has rendered the locals completely deaf.

After the 15th century, we find few references to a terrestrial location of Paradise. As man started to circumnavigate the globe and explore the interiors of more continents, it became clear that finding Eden was not going to be a simple matter of traveling.

Mappa Mundi

Approximately 1100 mappae mundi (maps of the world) have survived from the Middle Ages; about 200 are separate maps; the rest are in books.

Maps of the world were obviously limited by knowledge of geography. This did not deter medieval cartographers, however, since maps existed for along time not as guides for travelers, but as diagrams of the layout of God's creation. Minutiae weren't as important as portraying the overall plan, or showing a particular feature. For instance, Gervase of Canterbury's Mappa Mundi was drawn up specifically to show the bishopric s and ecllesiastical foundations of England, Scotland and Wales.

One of the most common of the map designs was the T-O design, called that by modern scholars because it resembled those letters. The "T" was the division of the major landmasses with the enormous Asia topping Europe and Africa; "O" was the encircling Ocean.

Note that Asia is on top. When choosing proper positioning for the arrangements of the continents, the direction of the rising sun seemed to be a logical place to begin. East is therefore placed at the top of the maps, and the arrangement of things in their proper place on a map therefore was called "orienting."*

Cicero's Dream of Scipio (in which a vision of the world is viewed in detail) was very popular in the Middle Ages for what it had to say about the world and the divine. Macrobius' (5th century CE) Commentary on it was how many readers became familiar with it. Many copies of the Commentary include mappa mundi of the type therefore called Macrobian. The Dream includes a description of the various zones, cold to temperate to hot to temperate to cold. Only the temperate zones were considered habitable.

Fourteen manuscripts of Beatus of Liébana's (c.730-800) popular Commentary on the Apocalypse of St. John include the quadripartite-style map that squeezes the Antipodes into the extreme south.

The most famous and most detailed maps provide the most variety and data and start to approach the realism and usefulness of modern cartography. The symbolic value of the mappae mundi began to be replaced by the need for accurate information to aid in travel and, especially, navigation on the seas. The new "Portolan Charts" became far more valuable to have and reproduce, and the number of mappa mundi were produced less.

If you would like to see some maps from across the ages, a good start is the Imaginary Museum.

*An extra tidbit: "orient" comes to Middle English from Latin via French and the verb oriri, "to rise"; once in English it starts being used for the direction itself in which the sun rises.

The Antipodes

As the unknown becomes close and familiar, imagination must seek new realms further away. Modern fiction doesn't write about alien life on the Moon or Mars or Venus, since we now "know" those spheres. In the Middle Ages, it was assumed that fantastical lands and creatures existed "over there." As far lands such as Africa, for instance, began to be explored and found mundane, the fantastical was mentally placed in a more distant spot.

The Antipodes (literally "opposite feet": the place on the globe directly opposite to where you are standing)* fascinated the Middle Ages for both philosophical and geographical reasons. On the one hand, the idea had come to them from the Classical World, and so was difficult to dismiss. This was the place that held creatures out of legend: Cyclopes, dog-headed men, Sciopods whose single large foot could be used as an umbrella when they lay on their backs, Blemmyae with faces on their torsos. On the other hand, the Medieval idea of symmetry demanded that there be lands to the far south, balancing the known lands in the north. Especially as the idea of earth's roundness took shape, Africa wasn't enough to satisfactorily balance Europe and Asia.

The Antipodes were also a natural extension of the theory of "zones." Since it became very cold up north, and hotter as you went south, it was assumed that the temperate zone enjoyed by most of Europe had a counterpart below the equator which was equally inhabitable. Below that, of course would be the area that is opposite the Arctic: the Anti-Arctic, or Antarctic.

The term was first used by Plato in his Timaeus. It was first used in English in 1398 in John of Trevisa's translation of Bartholomaeus Anglicus' De Proprietatibus Rerum (On the Order of Things):
Yonde in Ethiopia ben the Antipodes, men that haue theyr fete ayenst our fete.
(Yonder in Ethiopia are the Antipodes, men that have their fete against our feet.)
Some in the Middle Ages used the image of upside-down men as a reason to reject the Earth as a globe and opt for a flat Earth. Plato had addressed this himself, however, in an assumption of orientation that he does not call gravity but that works the same way:
For if there were any solid body in equipoise at the centre of the universe, there would be nothing to draw it to this extreme rather than to that, for they are all perfectly similar; and if a person were to go round the world in a circle, he would often, when standing at the antipodes of his former position, speak of the same point as above and below; for, as I was saying just now, to speak of the whole which is in the form of a globe as having one part above and another below is not like a sensible man.
But sensible men apparently did not read the Timaeus, or never grasped the concept of "up" and "down" being relative to where you were standing. A universally accepted map of the world was unknown; maps of the world typically took one of four forms, which we will look at tomorrow.

*Have fun finding your antipodal point here.
